Single chip 8 to 32-core OCTEON II™ MIPS64 Processors provide up to 48 GHz of 64-bit compute with unmatched L3-L7 Data and Security Acceleration to deliver 40Gbps of throughput while slashing power consumption for next generation Internet infrastructure applications

MOUNTAIN VIEW, Calif., May 11, 2010 – Cavium Networks (NASDAQ: CAVM), a leading provider of semiconductor products that enable intelligent processing for networking, communications, and the digital home, today unveiled a new family of processors which deliver unprecedented compute performance and application acceleration for borderless enterprise, mobile internet infrastructure and secure data center and cloud computing applications. The OCTEON II CN68XX/67XX processor families integrate 8 to 32 enhanced MIPS64 cores with up to 48GHz of 64 bit compute power in a single chip combined with over 85 L3-L7 application and security acceleration engines, virtualization features, 100Gbps of connectivity, and a revolutionary new Real Time Power Optimizer™ that dynamically adjusts power depending upon the application-level processing requirement. This level of compute is greater than 3x of next-generation alternative processors and enables OEM customers to achieve the highest level of rich, secure services with very low latency and power consumption at up to 40Gbps using a single OCTEON II chip and up to 100Gbps using multiple chips. The new OCTEON II processors also deliver up to 4x higher performance over the market-leading OCTEON Plus processors in a fully software compatible fashion enabling OEM customers to re-use existing software and system designs to easily upgrade their existing systems for higher performance. The OCTEON product line is the industry’s #1 embedded multi-core processor line designed into enterprise, data center and service provider equipment including routers, switches, appliances, 3G/4G wireless base stations, RNCs, xGSNs, evolved packet core, services gateways, DPI equipment, storage switches and intelligent server adapters.

Rapid adoption of data center and cloud computing initiatives coupled with dramatic traffic growth in both wired and mobile networks demands an unprecedented level of application security, compute and services at line rates up to 40Gbps. Concurrently, energy usage is becoming a dominant factor driving data-center and enterprise cost and capacity, requiring next generation networking solutions to fit in the smallest and most energy efficient footprint. Additionally, with the explosive increase in multi-media/video and real-time, interactive content and transactions, it is imperative to ensure low-latency, low-jitter delivery of applications and services across all networks. These critical inflection points in today’s hyper networks require highly advanced technology with a tremendous amount of compute and application specific acceleration at very high line rates.

The OCTEON II CN68XX and CN67XX 8 to 32 core MIPS64 processors deliver up to a 4x performance increase and up to 3x improvement in performance/watt over OCTEON Plus processors, enabling Cavium’s OEM customers to deliver breakthrough next generation solutions which address these critical inflection points, in an optimized, energy efficient manner. Additionally, the OCTEON II processors are supported by Cavium’s 3rd generation multi-core software development kit (SDK) and the broadest embedded multi-core ecosystem with over 50 vendors delivering OSs, tools, application software and stacks, hardware sub-systems, complementary silicon as part of the Multicore Partnership for Accelerated Customer End-solutions (PACE).

Supporting Analyst, Customer and Company Quotes
“Through its OCTEON processor line and an impressive set of customer wins, Cavium has been the fastest growing embedded processor vendor over the last few years,” said Linley Gwennap, Principal Analyst at The Linley Group. “Cavium’s track record of delivering three generations of multicore products within five years, all with market-leading performance, assures customers that their R&D investment will be protected and enables them to benefit from the significantly increased performance, power efficiency, and powerful acceleration capabilities of these processors.”

“RadiSys customers are facing increasing processing requirements to meet their next-generation performance needs, so we are pleased to see the significant increase in compute density, throughput and service features of the new Cavium CN68XX OCTEON II processors, ” said Anthony Ambrose, Vice President and General Manager, Communication Networks, RadiSys. “As the leader in ATCA solutions, we are at the forefront of delivering innovative 4G solutions with our Promentum ATCA 4.0 platform. The OCTEON CN68XX will help RadiSys continue to provide our customers with cutting-edge solutions.”

“SonicWALL’s recently announced technology, Project SuperMassive, uses Cavium’s OCTEON Plus to deliver unmatched performance and scalability up to 384 cores and 40Gbps for full DPI and security processing in a compact, energy efficient architecture,” said Matt Medeiros, CEO of SonicWALL. “The OCTEON II CN68XX will enable us to scale to 1024 cores and achieve well over 100Gbps of full malware protection so customers no longer have to compromise performance for security.”

“This new family of products defines a new performance, features and cost paradigm for equipment vendors targeting the massive upgrade cycle of the network infrastructure for 3G/4G wireless, cloud computing and data center applications. With over twice the per-core control plane performance, new hardware acceleration and a dramatic increase in overall throughput, the OCTEON II CN68XX significantly enhances our competitive position and increases the breadth of applications that we address while reducing cost and power consumption,” said Syed Ali, President and CEO, Cavium Networks. “These capabilities are essential to support the rapid growth in voice, video and data traffic and enable new classes of innovative applications that were simply not possible previously.”
